Nonlinear Mechanics and Predictable Bifurcation of Multi-Cell Kresling Origami Chains
Songlin Yue, Leo de Waal, David Garcia Cava +1
Meta-structures that display axial-twist coupling can be achieved through the emerging kinematics in Kresling origami patterns. A central challenge in these structures is understan…
How Geometry Tames Disorder in Lattice Fracture
Matthaios Chouzouris, Leo de Waal, Antoine Sanner +3
We investigate the fracture behavior of pre-cracked triangular beam-lattices whose elements have failure stresses drawn from a Weibull distribution. Through a statistical analysis…
Architecting mechanisms of damage in topological metamaterials
Leo de Waal, Matthaios Chouzouris, Marcelo A. Dias
Architecting mechanisms of damage in metamaterials by leveraging lattice topology and geometry poses a vital yet complex challenge, essential for engineering desirable mechanical r…
Cracking Down on Fracture to Functionalise Damage
Leo de Waal, Matthaios Chouzouris, Marcelo A. Dias
In this work we propose a novel relationship between topology and damage propagation in Maxwell lattices that redefines fracture as a functional design feature rather than mere deg…
